Separating Business Process from User Interaction in Web-Based Information Commerce

In Web-based information commerce it is diffcult to disentangle presentation from process logic, and sometimes even data is not separate from the presentation. Consequently, it becomes crucial to define an abstract model for business processes and their mapping into an active user interface presentation, using the principle of separation of concern. We endeavor to extend XSLT to accommodate the separation of process information from the data structure and presentation. We support declarative design further by a language designed to concisely specify information commerce processes. The isolation of the aspects of data, process and presentation makes it easier for developers to work independently and to focus on their primary responsibility.
